MuseDAC+ | Audio and I/O HAT for Raspberry Pi | MuseumTech

Why MuseDAC+

GPIO stays free. Existing DAC HATs occupy almost all pins. MuseDAC+ exposes I/O instead of taking it away.

One image for every installation. Hostname and settings live in the EEPROM on the board, not in the OS. Cloning an SD card is enough.

Connect speakers directly. Integrated 2 × 3 W amplifier, with no separate amplifier required.

Ambience and status in one. RGB LED strip output for lighting and status indication.

Analogue sensors. 8 × ADC channels for buttons, potentiometers, distance or light sensors.

Where it is used

MuseDAC+ is the standard platform inside every MuseumTech installation: audio points, object information screens and interactive displays. The same board runs in escape rooms, where it drives sound, lighting and puzzle sensors from one Raspberry Pi, and in retro arcade systems, where it handles audio, marquee lighting and control inputs without a second controller.

Because every installation shares one OS image, deployment and maintenance across multiple locations comes down to writing the EEPROM and cloning an SD card.

Specifications

• Raspberry Pi HAT with PCM5122 audio DAC
• 2 × 3 W integrated class-D speaker amplifier
• RGB LED strip output for ambient and status lighting
• Onboard status LED and I/O expander for additional digital inputs and outputs
• 8 × ADC channels for analogue sensors
• Onboard EEPROM: configuration, hostname and installation-specific settings live on the board, not in the OS image
• All remaining GPIO pins stay available for the installation

Applications

Museum audio points, object information with sound, interactive displays, escape room control, retro arcade cabinets and light installations with sensor input.

Ordering

MuseDAC+ is produced in small batches. Lead time and price depend on quantity and configuration. Request a quote for bare boards, kits with Raspberry Pi and enclosure, or complete installations.

Frequently asked questions

Which Raspberry Pi models are supported?
Raspberry Pi 4 and Raspberry Pi 5.

Does it work with standard Raspberry Pi OS?
Yes. Audio and I/O are enabled through a device tree overlay; no custom kernel is needed.

Can I buy a single board for my own project?
Yes. Single boards and small quantities are available on request.

What do I need to change when adding a new installation?
Only the EEPROM contents. The OS image stays identical across all installations.
